[michaelyeager-wf]

Notes

This PR adds the following:

• [Commit 1] The TracerProvider API, which includes the following:
  • TracerProvider, which centralizes state, settings, and defaults for Tracers created.
  • Sampler, which determines whether a Span should be sampled and sent for collection.
  • SamplingResult, which is the decision made by a Sampler regarding a Span.
  • InstrumentationLibrary, which represents versioning metadata within applications which use multiple implementations of OpenTelemetry.
  • AlwaysOnSampler, a default sampler which always samples.
  • AlwaysOffSampler, a default sampler which never samples.
• [Commit 2] A format make target which formats all library code and tests. This commit includes the results of running the make target.
